ABRAM NELSON, OF NEW YORK, N. Y.

STAPLE.

@PECIPIQATION forming part of Letters Patent No. 319,607, dated June 9, 18185.

Application filed July 9, 1883. (N0 model.)

To all whom it may concern:

Be it known that I, ABRAM NELsoN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Improvement in Staples, of which the following is a description.

This invention is an improvement in book staples intended especially for binding the strands of wire fences to the post or framing; and it consists in certain features of construction, which will be hereinafter described and claimed.

In the drawings, Figures 1 and 2 are perspective views of my staple, the latter having the body notched at the vertices of its angles.

Heretofore hook-staples have been made comprising a body and a hook, the body being serrated transversely on one or more of its siddes, and having its point drawn to a chisele ge.

My improved staple consists of a body, A, and a hook,]3. The body A is made equilateral and rectangular in cross-section, and has its extremity I) formed to what,-for convenience of reference, I term a needle-point. This point is formed by drawing the sides gradually and equally downward, so that said pointb will lie in the axial center of the body.

On one side of the body A, near its upper end or head, B, I form a shoulder, a, which faces toward the needle-point, as shown. The hook G has its shank united with the body at a point slightly above the shoulder a, as shown. This shoulder a provides a better seat for the wire, and operates to prevent the staple being driven so far into the post or other support as to embed the wire therein, and so tend to cut or fracture the wire by acutely bending it, as will be understood from the drawings.

The hook C, I form circular in cross-section, so it will not bend in driving, and in case it should strike a knot or other obstruction it will be forced directly through it, whereas any angular formation would give the hook a tendency to veer off in one direction or another.

In the use of achisel-pointedbody the staple needs be driven into the post or other support relatively to the direction of the grain thereof, so that the hook will be necessarily in line with the grain. By my improvement the staple may be driven independently of the grain of the wood of the support, so that the hook may be arranged vertically, horizontally,or at any intermediate angle desired;

Another important advantage in the form of my staple body over the chisel-pointed one is that the latter when driven into a support spreads the timber, and in a short time water entering the cracks so made will rust the body and cause it to become loose in a short time, so that a little strain upon the wire will withdraw the staple, whereas in my form of body the timber closes snugly against it on all sides.

I prefer,in order to give the body astronger frictional hold,to notch it at the vertices of its angles, the remainder of its surface remaining smooth, so that the body may be easily driven. These notches a, it will be seen, distinguish from the serrations extending transversely of the sides of the body, and are advantageous thereover in the following respect: The serrations tend to weaken the body at the crosssect-ional point where they are formed,whereas the notches produce no appreciable weakening of the part,and at the same time operate to add the desired friction to the body. To further avoid any weakening of the body by reason of these notches, I stagger themthat is, form the notches in each edge or vertex alternately with those in the adjacent ones-and am thus able to get the maximum degree of friction with the maximum strength, and I avoid all possibility of bending of the body while being driven-an objection which lies to those staples serrated transversely across one face.

I am aware that staples formed with bodies and hooks are not new; also, that such bodies have been formed rectangular in cross-section, and have had one or more of their faces serrated transversely, and I do not claim such construction as my invention; but,

Having thus described my invention, what I claim as new is 1. The improved staple comprising the body made equilateral and rectangular in cross section, and having its lower extremity drawn to a needle-point located in the axial center of the body, the said body being formed on one side with a shoulder, a, near its upper end or head, and the hook made circular in cross ICO section, and having its shank united to the on one side, near its upper end or head, with body at a point slightly above the shoulder a, a shoulder, a, and the hook made round in substantially as and for the purposes specified. cross-section, and having its'shank united with 2. As a new and improved article of manuthe body at a point slightly above the shoulder 5 fZcture, a hook-staple consisting of the body a, substantially as set forth.
